Abstract
Description
- This application is the United States National Phase of PCT Appln. No. PCT/DE2018/100094 filed Feb. 6, 2018, which claims priority to German Application Nos. DE102017104562.7 filed Mar. 6, 2017 and DE102017129269.1 filed Dec. 8, 2017, the entire disclosures of which are incorporated by reference herein.
- The disclosure relates to a hybrid module for a (hybrid) powertrain of a motor vehicle, such as a passenger car, truck, bus or some other commercial vehicle, having a housing, a separating clutch, and an intermediate shaft. A separating clutch rotating component, which is coupled to or can be coupled to an electric machine, is connected for conjoint rotation to the intermediate shaft, and the intermediate shaft is mounted by means of two support bearings in such a way as to be rotatable about a rotational axis relative to the housing. Moreover, the disclosure relates to a hybrid powertrain having the hybrid module.
- Prior art of the type in question is already sufficiently well known. WO 2016/070 878 A1, for example, discloses a hybrid module for a powertrain of a motor vehicle, having an electric drive motor, which is integrated into the hybrid module.
- Moreover, there is a known practice of monitoring the operating states of the electric machines of these hybrid modules. In principle, it is possible for this purpose to use various sensor devices in order, for example, to detect the rotational speed or a position of a rotor of the electric machine.
- However, one disadvantage of known hybrid modules is that a relatively large amount of installation space is occupied by the sensors of the sensor devices. This disadvantage is aggravated by the previously implemented arrangement of the sensor devices.
- Example embodiments broadly comprise support bearings arranged at a distance from each other in the axial direction, i.e. along the rotational axis, such that a receiving space is formed axially between them, wherein at least one part of a sensor device is arranged/accommodated/positioned in the receiving space. Through the skillful use of this installation space, which is available in any case, existing hybrid modules without a sensor device can be adapted easily without necessarily having to make available additional installation space. A compact design of a hybrid module, which can nevertheless be adequately monitored, is thus created.
- In this respect, the housing may have a partition wall extending in a radial direction, and the two support bearings may be mounted/held on a radial inner side of the partition wall. For example, a bearing outer ring of the respective support bearing is in each case mounted/held on the radial inner side of the partition wall. The support bearings are thereby mounted particularly firmly.
- The partition wall may have a sleeve region, which is arranged radially to the inside of a plurality of friction elements of the separating clutch. The support bearings are mounted (e.g. directly) on a radial inner side of the sleeve region. The sleeve region may be connected to the inside, in a radial direction, of a radially extending disk region of the partition wall. The disk region per se is arranged axially offset relative to the separating clutch/to friction elements of the separating clutch. Utilization of the installation space is thereby further optimized. The support bearings may be arranged directly or indirectly on a radial outer side of the intermediate shaft, which is designed as a hollow shaft or a solid shaft.
- As regards the sensor device, it may include at least one sensor, or a plurality of sensors, which sensor/s is/are arranged in the receiving space. This keeps the structure of the sensor device particularly simple. The at least one sensor may be designed to detect a rotational speed (/angular speed), a temperature, a torque and/or a position, e.g. an angular position. The sensor may be designed as a resolver. A sensor of particularly compact design is thereby integrated into the receiving space. The at least one sensor is connected/coupled (for data transmission) to an evaluation unit of the sensor device by means of a wireless link or, as a further preference, by means of a wired link.
- According to an example embodiment, a plurality of sensors in the form of temperature sensors of the sensor device are provided in the receiving space. In this case, each temperature sensor may make contact with a bearing ring of one of the support bearings, with the result that it detects the temperature of the respective bearing ring. According to another example embodiment, the at least one sensor is designed as a rotational speed sensor/rotation angle sensor, e.g. in the form of a resolver. The rotational speed sensor/rotation angle sensor is connected in a fixed manner to the housing and interacts with a transmitter connected for conjoint rotation to the intermediate shaft.
- In an example embodiment, the support bearings may have different diameters and, may be arranged on different steps/offsets of the intermediate shaft. If a slave cylinder used to actuate the separating clutch, e.g. in the form of a concentric slave cylinder (CSC), is positioned radially between the support bearings and a plurality of friction elements of the separating clutch, the existing installation space is used even more completely.
- Moreover, the disclosure relates to a hybrid powertrain for a motor vehicle, having the hybrid module according to the disclosure in accordance with at least one of the embodiments described above. In other words, according to the disclosure, sensors (sensor device) are integrated into a hybrid module, which may be designed as a P2 hybrid system. According to the disclosure, a sensor system (sensor device; preferably for detecting a speed/rotational speed, temperature, torque, position or the like) is arranged between two support bearings of an intermediate shaft.

As regards the different illustrative embodiments described in greater detail below, it should be noted that, in principle, all the illustrative embodiments are constructed and function in accordance with the first illustrative embodiment and therefore, for the sake of brevity, only the differences with respect to the first illustrative embodiment are described.
- In connection with
FIG. 1 , the structure of the hybrid module 1 according to the disclosure, in accordance with a first illustrative embodiment, is particularly clearly visible. In operation, the hybrid module 1 is part of a hybrid powertrain of a motor vehicle. The hybrid module 1 may be inserted between anoutput shaft 20 of an internal combustion engine and a transmission, when viewed along the torque transmission path. In typical fashion, the hybrid module 1 has a clutch device including at least one component clutch, or a plurality of component clutches, of which only one (first) separatingclutch 3 is illustrated, for the sake of clarity. The (first) separatingclutch 3 is used to selectively couple theoutput shaft 20 to anintermediate shaft 4 of the hybrid module 1 for conjoint rotation. The hybrid module 1 also has, in typical fashion, an electric machine/electric motor. In this embodiment, the electric machine is arranged axially parallel, i.e. with an axis of rotation of its rotor parallel to an axis of rotation 8 of theintermediate shaft 4/of the output shaft 20 (crankshaft). In this illustrative embodiment, the electric machine can be regarded as a component of the hybrid module 1 but, in principle, can also be regarded as a component separate from the hybrid module 1. - On a side facing the
output shaft 20, the hybrid module 1 of the first illustrative embodiment has a torsional vibration damper in the form of adual mass flywheel 22. InFIG. 1 , thedual mass flywheel 22 is already connected for conjoint rotation to theoutput shaft 20. Thedual mass flywheel 22 is connected on the input side to theoutput shaft 20. On the output side, thedual mass flywheel 22 is connected for conjoint rotation to arotary component 15, referred to below as thesecond rotary component 15, of the first separatingclutch 3. - The
first separating clutch 3 is embodied as a friction clutch. In this illustrative embodiment, the first separatingclutch 3 is embodied as a dry clutch but, in principle, can also be embodied as a wet clutch. Afirst rotary component 5 of the first separatingclutch 3, said component being provided adjacent to thesecond rotary component 15, interacts via a plurality offriction elements second rotary component 15. In a coupled position of the first separatingclutch 3, the tworotary components friction elements clutch 3, thefriction elements rotary components rotary components - For example, the first separating
clutch 3 is configured as a multiplate friction clutch. Thus, eachrotary component friction elements first rotary component 5 has afirst carrier 23, designed as an inner carrier/inner plate carrier. A plurality offirst friction elements 13 a is mounted for conjoint rotation on thisfirst carrier 23, namely on a sleeve-shaped supportingregion 24 of thefirst carrier 23. Thefirst friction elements 13 a are furthermore mounted on the supportingregion 24 of thefirst carrier 23 in such a way as to be movable relative to one another in the axial direction. For this purpose, thefirst carrier 23 has formed teeth, on which thefirst friction elements 13 a are mounted for conjoint rotation and in a manner which allows axial movement. Asecond friction element 13 b of thesecond rotary component 15 is in each case arranged between two adjacentfirst friction elements 13 a. Thesecond rotary component 15 has asecond area 25 in the form of an outer carrier/outer plate carrier, which holds thesecond friction elements 13 b for conjoint rotation and in a manner which allows them to move axially relative to one another. - The rotor (not illustrated specifically here, for the sake of clarity) of the electric machine is furthermore coupled in driving fashion to the
first rotary component 5 of the separatingclutch 3. For this purpose, the rotor shaft of the rotor is coupled to thefirst rotary component 5 by means of a traction means 26 (in this case a belt but, as an alternative, could also be a chain etc.). Thefirst rotary component 5 has a traction means mountingregion 27, which receives the traction means 26 in positive and/or frictional engagement. The use of chains has proven useful at this point, for example. The mountingregion 27 is arranged radially to the outside of the supportingregion 24 and of thefriction elements first carrier 23 thus also forms a rotor/belt pulley carrier. - By means of its
first carrier 23, thefirst rotary component 5 is rotationally connected to anintermediate shaft 4 which, in turn, is mounted so as to be rotatable about the axis of rotation 8. In this illustrative embodiment,serrations 28 are used to establish the connection for conjoint rotation between thefirst carrier 23 and theintermediate shaft 4. In operation, theintermediate shaft 4 serves in typical fashion to connect thefirst rotary component 5 to a further component clutch of the clutch device, e.g. to a component clutch of a double clutch of the hybrid module 1. - The
intermediate shaft 4 is mounted in such a way as to be rotatable relative to a housing 2 of the hybrid module 1. For this purpose, twosupport bearings dual mass flywheel 22 in the axial direction than a second support bearing 7. Bothsupport bearings support bearings partition wall 11 of the housing 2. For this purpose, thepartition wall 11 forms asleeve region 14, which extends in the axial direction and on the radialinner side 12 of which the twosupport bearings support bearing outer ring sleeve region 14/on thepartition wall 11. - The
support bearings sleeve region 14 is of stepped design. The first support bearing 6 is mounted by means of the bearingouter ring 29 a thereof on a first step; the second support bearing 7 is mounted by means of the bearingouter ring 29 b thereof on a second step, which is widened radially outward relative to said first step. In corresponding fashion, thesupport bearings intermediate shaft 4. A first step of theintermediate shaft 4 serves to receive the first support bearing 6/a bearinginner ring 30 a of thefirst support bearing 6 and is of smaller dimensions radially than a second step, which serves to receive the second support bearing 7/a bearinginner ring 30 b of the second support bearing 7. - According to the disclosure, a receiving
space 9 is now formed between the twosupport bearings sensor device 10. This is also particularly clearly visible inFIG. 2 . In this context,different sensors 17 of thesensor device 10 for mounting in this receivingspace 9 are illustrated in connection withFIGS. 3 to 5 . - In
FIG. 3 , a plurality ofsensors 17 of thesensor device 10 are arranged in the receivingspace 9. Thesensors 17 are each configured as temperature sensors. Thesensors 17 are respectively connected to one of the bearing rings 29 a, 29 b, 30 a, 30 b. Thus, an individual (first)sensor 17 is mounted in contact on the bearingouter ring 29 a of thefirst support bearing 6. A further (second)individual sensor 17 is mounted in contact on the bearingouter ring 29 b of the second support bearing 7. A further (third)sensor 17 is mounted in contact on the bearinginner ring 30 a of thefirst support bearing 6. A further (fourth)sensor 17 is mounted in contact on the bearinginner ring 30 b of the second support bearing 7. In this illustrative embodiment, eachsensor 17 is furthermore connected for data transmission and power transmission to an evaluation unit of thesensor device 10 by a wired link, a section of which is indicated here by means of acable 18. For the sake of clarity, the evaluation unit is not illustrated specifically. The wired link passes through thepartition wall 11 in the radial direction and/or at least partially in the axial direction relative to the axis of rotation 8. - In
FIG. 4 , only asingle sensor 17 of thesensor device 10 is arranged in the receivingspace 9. InFIG. 4 , thesensor 17 is configured as a rotational speed sensor. Thesensor 17 interacts with atransmitter 31, wherein thetransmitter 31 forms a component that can be detected metrologically by thesensor 17. Thetransmitter 31 is arranged radially to the inside of thesensor 17. Thesensor 17 is mounted in a fixed manner on thepartition wall 11/housing 2. The measuring zone of thesensor 17 is directed inward in the radial direction toward thetransmitter 31. Thetransmitter 31 is connected for conjoint rotation to theintermediate shaft 4. Thetransmitter 31 is mounted on anouter side 16 of theintermediate shaft 4. It is thereby possible, in particular, to detect a rotational speed/angular speed of theintermediate shaft 4. Thetransmitter 31 is furthermore designed as a transmitter wheel. Thetransmitter 31 thus has a plurality of projections/raised portions distributed around the circumference, which also allow detection of the (angular) position of theintermediate shaft 4 in operation. A rotational speed/angular speed and position of the rotor can also be inferred by virtue of the rotary connection to the rotor. - In connection with
FIG. 5 , as inFIG. 4 , asingle sensor 17 of thesensor device 10 is implemented in the form of a rotational speed sensor. Thesensor 17 of the variant illustrated inFIG. 5 differs from thesensor 17 in the variant illustrated inFIG. 4 in that the measuring zone thereof is aligned in the axial direction. Thetransmitter 31 projects beyond thesensor 17 in the radial direction in a certain region of overlap, thus enabling thesensor 17, in turn, to detect the raised portions of thetransmitter 31 in the form of the transmitter wheel. - As can furthermore be seen in
FIG. 1 , the first separatingclutch 3 can be actuated by means of aslave cylinder 19. Theslave cylinder 19 is embodied as a concentric (annular) slave cylinder 19 (CSC). Theslave cylinder 19 is mounted in a manner fixed relative to the housing, namely fixed relative to thepartition wall 11. Theslave cylinder 19 has acylinder housing 32, which is arranged and secured on a radial outer side of thesleeve region 14. An (annular)piston 33 is mounted movably in thecylinder housing 32. A preloadingspring 37 acts on thepiston 33 in an axial direction. Thepiston 33 furthermore interacts with anactuation bearing 34, and this actuation bearing 34, in turn, interacts with apressure pot 35. Owing to the design of the first separatingclutch 3 as a normally closed/normally engaged clutch, thepressure pot 35 is preloaded by adiaphragm spring 36 in such a way that, in an unactuated state of theslave cylinder 19, it forces the first separatingclutch 3 into its coupled position by pressing thefriction elements slave cylinder 19 is therefore implemented as a clutch release device/clutch release system. InFIG. 1 , thediaphragm spring 36 is illustrated in dashed lines in further pivoted positions. In the region of its pivoting point, thediaphragm spring 36 is connected in a fixed manner axially to/supported in a fixed manner axially on thefirst rotary component 5. Thus, thediaphragm spring 36 is clamped in the axial direction relative to thefirst rotary component 5. A modulation spring can optionally also be present in addition. - A further, second illustrative embodiment of the hybrid module 1 according to the disclosure is illustrated in connection with
FIGS. 6 and 7 . As can be seen here, it is also possible, in principle, for theintermediate shaft 4 to be of multipart design. Theintermediate shaft 4 helps to form a flywheel/acounterpressure plate 39 of a further clutch 38/component clutch of the clutch device. Thecounterpressure plate 39 is connected for conjoint rotation to a tubular component/main body 40 of theintermediate shaft 4. Moreover, the torsional vibration damper is here in the form of a single mass flywheel. Thefirst carrier 23 is also connected to theintermediate shaft 4 by means of riveting. - In connection with
FIG. 8 , it is furthermore also possible to construct the hybrid module 1 in accordance with the coaxial type, rather than with the axially parallel type. In this illustrative embodiment, theelectric machine 21 is incorporated directly into the housing 2 of the hybrid module 1. In particular, astator 41 and therotor 42, interacting therewith, of theelectric machine 21 are integrated into the housing 2. Therotor 42 is mounted directly on the mountingregion 27 of thefirst carrier 23. Thefirst carrier 23 thus directly forms a rotor carrier. Moreover, theintermediate shaft 4 is of multipart design, as inFIGS. 6 and 7 . Thecounterpressure plate 39 is, in turn, connected for conjoint rotation to themain body 40. Moreover, thesensor 17 accommodated in the receivingspace 9 is designed as a resolver. - In other words, according to the disclosure, the installation space (receiving space 9) between the
support bearings intermediate shaft 4 is used for the measuring sensors (sensor device 10). Thisinstallation space 9 has the advantage that a very wide variety of sensors can be installed at this point. These can besensors 17 for rotational speed, temperature (e.g. for monitoring bearings), torque, position (resolver) or the like, for example. By virtue of the installation position of thesensors 10, it is possible to install bothwireless sensors 10 andsensors 10 withcables 18 since these can be routed “to the outside” via thepartition wall 11. Both radially and axially operating systems are conceivable. Moreover, the installation location (receiving space 9) is protected from contamination. In the present case, one may highlight the possibility, in particular, of relocating the resolver (sensor 17) for a coaxially arrangedelectric machine 21, which hitherto has occupied a large amount of installation space in an unfavorable location, to the statedinstallation location 9. The installation position for the measuringsensors 10 is suitable both for coaxially arranged hybrid modules 1 and for axially parallel arrangements. Moreover, it is equally suitable for 48V and for high voltage systems. - In principle, a K0 clutch/engine separating clutch (first separating clutch 3) which is normally closed is used as an initial basis in an example illustrative embodiment. The embodiment of this clutch 3 as a dry multiplate clutch or wet clutch is correspondingly possible. The electric machine is arranged in an axially parallel manner and is coupled to the
K0 3 by a belt drive, chain drive, etc., for example. A rotor/belt pulley carrier (first carrier 23) of theK0 3 is at the same time embodied as an inner plate carrier. Thecarrier 23 may be designed with formed plate teeth. The plate pack (totality of first andsecond friction elements K0 3 is preloaded by means of adiaphragm spring 36, optionally including a modulation spring. TheK0 3 may be actuated by means of an annular piston CSC (slave cylinder 19). There may be a bearing preloading spring therein. A coaxialelectric machine 21 is also possible in corresponding fashion. The DMF (dual mass flywheel 22) may have a flange with or without a clamping device. -

Reference sign 2 denotes a retainingring 43 for supporting a bearing 46 of theouter plate carrier 25 and a diaphragmspring support plate 44.Reference sign 39 denotes a flywheel, which is formed integrally with a flange and teeth for connection to a shaft (intermediate shaft 4).Reference sign 36 denotes a diaphragm spring, which has a diameter smaller than an inside diameter of driver teeth.Reference sign 4 denotes a shaft, which can be embodied as a hollow shaft or a solid shaft.Reference sign 11 denotes a partition wall, which has formedapertures 45 with a thread for screwing to a housing 2. - 1 hybrid module
